Collector insights
- Design heritage: Jody Clark, Aaron West is credited as the designer for the Circulating commemorative coins series. Designer attribution helps distinguish this issue from later restrikes or unofficial copies that reuse only the motif.
- Struck at: Royal Mint, Llantrisant, United Kingdom (1968-date). Confirm the mintmark on your example before comparing prices — same-year issues from different mints often trade at very different levels.
- Low mintage: Only 81,608 pieces reported. This puts the issue into key-date territory for its series; expect steep grade-based price scaling and a higher counterfeit risk — provenance and third-party grading matter.
- Catalogue reference: Listed as
Sp#H48, KM#1430. Use this reference code when cross-checking auction archives, dealer inventories, and standard printed catalogues.
